MC74LVX541DWG

Overview

The MC74LVX541DWG is an octal bus buffer fabricated with advanced high-speed CMOS technology. It operates within a supply voltage range of 2.0 V to 3.6 V and features noninverting outputs controlled by two independent output enable inputs (OE1, OE2). The device provides balanced propagation delays and high noise immunity. Inputs tolerate voltages up to 5.5 V, enabling interface between 5.0 V systems and 3.0 V systems. It is housed in a 20-pin SOIC package.

Feature Summary

• Provides high-speed operation comparable to Bipolar Schottky TTL while maintaining low power dissipation.
• Features dual output enables that place terminal outputs in a high-impedance state when asserted high.
• Includes internal three-stage circuitry for high noise immunity and stable output performance.
• Inputs tolerate voltages up to 5.5 V, facilitating direct interfacing between 5.0 V and 3.0 V logic systems.

Applications

• Bus-oriented memory and address drivers
• Clock drivers
• Buffering oscillators

Procurement Notes

Verify the specific ordering suffix 'DWG' corresponds to the SOIC-20 package and lead-free status. Confirm the manufacturer part number matches the datasheet exactly. Ensure the component meets RoHS compliance requirements for your assembly process. Check for any specific handling instructions related to moisture sensitivity level.

Selection Notes

Select this component for applications requiring octal buffering with dual independent control. It is suitable for designs needing voltage translation from 5.0 V inputs to 3.3 V or 2.5 V systems. Consider its low quiescent current and high noise immunity for signal integrity in noisy environments. Verify package availability if space constraints require surface-mount installation.

Part Context

This part belongs to the LVX series of advanced high-speed CMOS logic devices. It is functionally compatible with other standard logic families but optimized for lower voltage operation. The octal configuration allows for efficient data bus management in complex digital systems.

FAQ

What is the maximum input voltage tolerance?

The inputs can tolerate DC voltages up to 5.5 V, allowing safe interfacing with 5.0 V logic systems even when the device is powered at lower voltages like 3.3 V.

How does the device handle unused outputs?

Unused outputs should be left open. Unused inputs must always be tied to an appropriate logic voltage level, either GND or VCC, to ensure proper operation.
